HOOK-AND-EYE FASTENER.

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed November 12, 1904. Serial No. 232,465.

To all whom it nwty concern:

Be it known that I, FRANK E. DE LONG, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Hook and-Eye Fasteners, of which the following is a specification.

This invention relates to an improvement in hook and eye fasteners, and its object is to provide means to prevent disengagement of a hook and an eye after the same have been engaged or interlocked.

The invention resides in the novel features of construction hereinafter described in the specification, particularly pointed out in the claims, and as illustrated in the accompanying drawing forming a part of this specification, and in which,

Figure I is a plan view of a couple of hook and eye fasteners disclosing my invention, the hooks and eyes of the respective fasteners being attached to the adjacent edges of an article of wearing apparel and being in engagement with each other;

Figure II is an enlarged plan view of the hook member of the fastener; and v Figure III is a side elevation of the same.

In the drawings,

1 designates the adjacent edges of an article of wearing apparel, to one of which edges eyes 2 of the form commonly known as loop eyes are secured, and to the other of which edges the hook members 8 of the fasteners are secured, said hook members being constructed in accordance with my invention.

The hook member of my hook and eye fastener is constructed of a single piece of wire bent so as to form the thread eyes 4: of the said member, also the shank 5 and the hill 6 of the hook. The shank of the hook consists of two portions of the wire arranged side by side and in contact, while the hill 6 of the hook consists of two portions of the wire forming the hook member arranged side by side and parallel to each other, as usual, but the said portions being separated and out of contact, as is shown most clearly in Figure II of the drawing. The separation of these wires is for the purpose of permitting compression and consequent movement of the said two portions of wire forming the bill of the hook toward and from each other when an eye is placed in engagement with or is disengaged from the said hook.

Upon the outer opposite sides of the bill of the hook, at points intermediate the extreme member of the attachment, the projections end of the bill and the bight or loop of the hook, projections 7 are formed. As illustrated, these projections are curved and are formed by compressing or flattening out the metal of the bill of the hook or a portion of it. It is to be understood, however, that these projections may be formed upon the sides of the bill of the hook in any desired manner.

The projections upon the sides of the bill of the hook must be formed so that the distance from side to side of such'bill where the said projections are formed is greater than the diameter of the eye of the loop eye of the attachment, so that when once the hook and eye are in engagement they will not become accidentally disengaged.

It will be understood that when the eye is pushed or forced over the bill of the hook, the separated portions of wire which are arranged side by side to form the bill of the hook will be compressed or moved toward each other so as to permit the engagement of the hook and eye; and that in disengaging the hook and eye, the same compression or movement of the separated portions of wire forming the bill of the hook takes place, and that after an eye has passed over the projections the compressed portions of the wire or metal constituting the bill of the hook, the said portions spring back to their normal positions.

In order to facilitate the engagement of the eye with or its disengagement from the hook curve from their respective ends gradually outward to their center, as is illustrated clearly in Figure II of the drawing.

It will be understood that many changes in details of construction may be employed without departing from the spirit of my invention; therefore I do not desire to be limited to the construction illustrated in the accompanying drawing.

Having thus described my invention, I claim- 1. The hook member of a hook and eye fastener constructed of a single piece of wire bent to form the shank and the bill of the hook, the said shank consisting of two portions of wire arranged side by side and in contact, and the bill consisting of two wires arranged side by side and parallel but separated or spaced from each other, and projections formed upon the outer sides of the said bill by flattening out portions of the metal of the said bill.

2. The hook member of a hook and eye fasand being curved outwardly gradually from their opposite ends toward their centers.

In testimony that I claim the foregoing as my invention, I have hereunto signed my name this 10th day of November, A. D. 1904.
